I'm not sure if I'm pregnant or not but I have a few questions that I'm afraid to ask my mother. I'm 18 and my boyfriend and I have been trying to have a baby. We did the deed on July 23rd 2014 and Today (July 30th 2014) I've been getting weird mood swings and becoming extremely irritated at everything and before I went to bed I started having this horrible sharp pain in my lower left side kinda near my hip bone. I was just curious to if this could be implantation or something else? I'm kinda scared and I've never been pregnant before.
